Which field type does a snapshot field get its data from?

A snapshot field in Quickbase is designed to capture and hold values from another field at a specific point in time, allowing users to track changes over time. The correct choice indicates that a snapshot field gets its data from a formula field. This is essential because formula fields compute their values dynamically based on the underlying data.

When you use a snapshot field and set it to capture the value of a formula field, it records the output of the formula at the moment the snapshot is taken. This is particularly valuable in scenarios where you want to maintain historical data without the influence of subsequent changes to the underlying records that the formula field depends on.

On the other hand, while summary fields, multiple choice fields, and lookup fields have specific functions, they do not serve the same role as source fields for snapshots. Summary fields aggregate data from related records, multiple choice fields allow for selection from predefined options, and lookup fields pull data from a related table but do not necessarily provide a computed or evaluated value at a particular moment like a formula field does. Hence, the most fitting source for a snapshot field is indeed a formula field, as it directly relates to the capturing of calculated data at a defined time.
